Table C–2: Default CH4 and N2O Emission Factors for Various Types of Fuel
| Fuel type | Default CH4 emission factor (kg CH4/mmBtu) | Default N2O emission factor (kg N2O/mmBtu) |
|---|---|---|
| Coal and Coke (All fuel types in Table C-1) | 1.1 × 10−02 | 1.6 × 10−03 |
| Natural Gas | 1.0 × 10−03 | 1.0 × 10−04 |
| Petroleum (All fuel types in Table C-1) | 3.0 × 10−03 | 6.0 × 10−04 |
| Fuel Gas | 3.0 × 10−03 | 6.0 × 10−04 |
| Municipal Solid Waste | 3.2 × 10−02 | 4.2 × 10−03 |
| Tires | 3.2 × 10−02 | 4.2 × 10−03 |
| Blast Furnace Gas | 2.2 × 10−05 | 1.0 × 10−04 |
| Coke Oven Gas | 4.8 × 10−04 | 1.0 × 10−04 |
| Biomass Fuels—Solid (All fuel types in Table C-1, except wood and wood residuals) | 3.2 × 10−02 | 4.2 × 10−03 |
| Wood and wood residuals | 7.2 × 10−03 | 3.6 × 10−03 |
| Biomass Fuels—Gaseous (All fuel types in Table C-1) | 3.2 × 10−03 | 6.3 × 10−04 |
| Biomass Fuels—Liquid (All fuel types in Table C-1) | 1.1 × 10−03 | 1.1 × 10−04 |
Note: Those employing this table are assumed to fall under the IPCC definitions of the “Energy Industry” or “Manufacturing Industries and Construction”. In all fuels except for coal the values for these two categories are identical. For coal combustion, those who fall within the IPCC “Energy Industry” category may employ a value of 1g of CH4/mmBtu.
